INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP 1. Safety 1.1. General The equipment has been designed and constructed according to D.P.R. n° 459 of 24th July 1996 (regulation for accomplishment of Norms 98/37/CEE, 91/368/CEE, 93/44/CEE and 93/68/CEE regarding the unification of States members laws in so far as machines are concerned). It has been designed and constructed according to European Norms UNI EN 292-1, UNI EN 292-2, UNI EN 292-2/A1, UNI EN 983, CEI EN 60439-1, CEI EN 60 204-1.
INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP 2. Principles of working FC/D and FAC/D series filters are used for water treatment for residential and industrial applications as well. All the materials are food grade and approved for drinking water. 2.1. Quartz-sand filters FC/D The filtration through a sand media is a mechanical process that allows to remove suspended solids (even of small dimensions) from water.

Keep the cards and everything contained inside the packaging. The media filter are shipped as separated: • in bags of 25 kg (35 liters approx) each or fraction anthracite • in bags of 25 kg each or fraction quartz sand • in bags of 25 kg (50 liters approx) each or fraction activated carbon 4.2.
INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP 4.4. Hydraulic connections (see DRAWINGS installation and components) In order to avoid shut-off during maintenance operations, an emergency by-pass line should be provided • Complete the line from inlet fittings to the raw water line. • Complete the line from outlet fittings (valve V2) to the treated water line. • Connect the drain valves (V1 and V5) to a floor drain.
INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP 4.5. How to load the media filter The media filter must be loaded inside the vessel afterthat the placing of the filter is completed or in the case the media have to be replaced. • Open both the side man-holes • Check that the filter nozzles are correctly fixed and not damaged.
INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP 5. End cycle and regeneration 5.1. End cycle The unit is equipped with 2 pressure sensors plumbed on inlet and outlet line of the filters; the sensors gauge the correspondent pressure (IN/OUT) and therefore also the differential pressure; when the pressure drop across the filtering bed reaches the value of 0.8 bar (80 kPa), the end-cycle is driven.
INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP The regeneration can also run in case of power failure, by hand-driving the lever of the pilot solenoid valves: the solenoid valve is closed when the lever is on parallel to the base and it is open when it is on perpendicular to the base itself. Naturally, the compressed air supplying (air controlled valves) or pilot water supplying (water controlled valves) must be assured.

Functions of the logical programmer The logical programmer Siemens serie LOGO handles the logical working of the whole unit. Its display allow the visualization of the status of the logical inputs (marked as I), the logical outputs (marked as Q), current time and date, the several messages enabled by the programme. It is also possible to modify the settings of the entered numerical parameters (marked as B).
INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP 6.2. Signals on the display of the programmer The report messages enabled by the programmer are visualized on the display one at a time, with a determinate priority. The buttons and are used to scroll the messages. The button is used to turn back to service visualizations.

INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP 8. Starting-up The starting-up of the unit consists of running a first regeneration cycle, during which the filtering media column will be filled of water, all automatic features will be checked and the unit will be prepared to start the service.
INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP 9. SERVICE & MAINTENANCE Normally, these units do not require any regular maintenance operation and there is not any consumption material to be currently replaced. The only parts that can be aged are the electrical components and moving parts, as listed : • the membrane of the automatic valves; after years, they can be aged and crack. • the solenoid valves can break down (electric) or can get dirty if the pilot fluid is not perfectly clean.
INSTRUCTIONS MANUAL AUTOMATIC FILTERS FC/D-DP -FAC/D-DP 9.2. Disposal In case of disposal of the unit or parts of it, it must be made according to local laws concerning the waste of the materials. Concerning media filter, they are natural products that, at origin state, can be disposed of as natural products. Whether the activated carbon had trapped special and particular substances, the carbon will be classified as same class of the trapped substances. 10.
